iOS suggestion - autolock settings

I normally keep autolock set to 1 minute. When I play a round of golf, I connect the phone to USB and change autolock to NEVER. At end of round I switch autolock back to 1 minute if I remember. If I forget then phone never locks and remains vulnerable to snooping and power drain.

It would be handy if there were two settings for autolock, one for when phone not connected to power, and a second for when phone is connected to power.

I have seen questions on Apple support about this but have not seen anyone from Apple indicating they would log a product improvement request.
